SASH-LOCK.

Specification of Letters Patent No. 15,857, dated October '7, 1856.`

To all 'whom t may concern: A e

Be it known that I, OWEN REDMOND, of Rochester, in the county of Monroeand State of New York, have invented a new and useful Improvement `inySash-Locks; and I do hereby declare that the following is a full,clear, and eXact description of the construction and operation of thesame, reference being had to the annexed drawings, forming part of thisspecification, in which- Figure l is a view showing interior of lockwith bolt protruding. Fig. 2 is a similar view showing bolt withdrawn.Fig. 3 is a view of outside of the lock. Fig. t is an edge view.

Similar letters denote the same part. The nature of my inventionconsists in combining a swinging bolt, and wedge operating slide, withina case, as will be hereinafter described, so that the protruding of thebolt and the securing of the same shall be due to the gravity of theoperating n slide.

The details of construction and operation are as follows: `In thedrawing `C is the case containing bolt B swinging on pin p, and asliding piece S, formed as shown in the drawing, having a small stud awithin slot b, of the case, so that the slide can be lifted The weightof the slide S, causes the ine clined plane d, to act on arm e of boltB, and project the tongue j", while the incline z', securely fastens thesaid bolt, as: shown in Fig. l. The raising of slide S, causes arm m ofsaid slide to lift arm e of the bolt and draw the tongue f within thecase.

What I claim as my invention and desire to secure by Letters Patent, is-

The swinging bolt B, in combination with the slide S, and case C,constructed, arranged and operating as described, so that the gravity ofthe slide shall shoot the bolt and maintain it in position.

In testimony whereof, I have hereunto signed my name before twosubscribing witnesses.
